generateHashLikeId.ts

const createId = (text = Date.now().toString().substring(0, 10)) => {
  const m = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j"]; // 0 ~ 9
  let hash = "";

  for (let i = 0; i < text.length; i++) {
    if (i > 6) {
      hash += text[i];
    } else {
      hash += m[Number(text[i])];
    }
  }
  return hash.toUpperCase();
};

createId() // example: BGFCIDD703
